My dad grew up on a farm up north. His dad, my Grandpa, was a respected veterinarian in their area. People from far and wide would come to his clinic with their critters for help. Grandpa had trained to be a small and giant critter vet. This meant he could work on pets and farm critters of all ages. In the section where dad grew up, there were even folks who owned zebras, reindeers, alpacas, and several more exotic critters. Grandpa treated them all and even made condo calls to farms in a wide area. After serving his community for almost three decades, it was time for Grandpa to hang his hat. Now, he likes spending his days at the cabin with Grandma and his different machines. Grandpa has a shed outback where he loves tinkering with different items. Last summer, I went for a visit and as we were laboring, Grandpa mentioned there was an issue with the furnace in the shed. He had tried checking the small furnace in this space, but he couldn’t figure it out. His worry was that he’d not manage to work in his shed once winter time comes because of the faulty unit. I am a trained Heating and A/C pro so this was right up my alley. I fetched my tool kit from the truck and began opening up the furnace in the shed. Grandpa was right there to watch me at work and I felt so fantastic to have his assistance. My old friend and I finally got to the root of the problem. A dirty air filter was obstructing ample air flow into the shed. All we had to do was upgrade this with a new air filter and the furnace was ready for the cold season.
